Explanation / Answer

Q1)

The AND (&&) operator will be evaluated last. The operations on left and right are evaluated and then the results are compared using &&.

Q2)

The first statement is not true, i.e, it is false. The OR (||) operator returns a TRUE value even if one of the operands is true.

Q3)

In C++, any non-zero value is TRUE. This can include a string also, like 'true'.

Q4)

The do...while loop will be executed atleast once because the condition is evaluated at the end of iteration. So, even if the condition tends to be false, the loop would have been executed atleast once.

Q5)

The third statement is false. The && operator needs two operands.
